The company has design and production capacity of UV exposure source, the use of high-pressure mercury lamp power have 350W, 500W, 1000W, 2000W, 3500W, 5000W, Idemitsu size is 4 “, 6”, 8 “, 12” circular beam, or 4 “, 6”, 8 “, 12”, 16 “, 20”, 24 “square beam. Light intensity and beam power by a mercury lamp varies in size and shape to 350W 4 “I-line circle of NUV output intensity beam of about 30mW / cm2, 1000W 6” I-line output beam intensity NUV party of about 40mW / cm2, uniformity of plus or minus 5%, half-width parallel light by different light diameter of about 1.5 to 3 degrees. homogenized beam to produce a lens array, doing pattern transfer exposure can effectively reduce the diffracted light to to achieve good resolution of the graphics.
